AIR-COOLING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 405,064, dated June 11, 1889.A

Application tiled .T anuary 4,1889. Serial No. 295,428. (No model.)

T0 @ZZ whom t may concern.'

Be itknown that I, JOSEPH L'. VOOD, of the city, county, andy State of New York, a citizen of the lUnited States, have invented certain new and useful Improvements in Air- Oooling Apparatus, of which the following is a specification.

This invention relates to an improved aircooling apparatus which is .to be used in connection with a refrigerating-machine for cooling and purifying the air of storage-warehouses, cellars, dre., the cooling apparatus being so constructed that a very effective purifying action is exerted on the air without loss of cold and that the different parts of the apparatus employed for cooling the air by chilled brine can be readily cleaned and replaced; and the invention consists of an aircooling apparatus which is composed of a number of wire screens that are suspended from T-shaped discharge pipes or heads provided with j et-openings for the brine, the screens communicating with said openings by twisted wires and adjustable conical plugs located on said twisted wires, so that the supply of brine to the distributing-screens can be regulated. The screens are suspended in a detachable manner from said distributingheads and the brine delivered from the screens to an inclined trough, by which the brine is returned to the refrigerating-machine for rechilling and redistribution.

In the accompanying drawings, Figure 1 represents a side elevation of my improved apparatus for cooling air by means of chilled brine, being shown in section through the collecting-trough. Fig. 2 is a vertical transverse section of the same on line .fr oc, Fig. l; and Figs. 3 and 4 are respectively a vertical longitudinal section through a part of the brine-discharging head and a vertical-transverse section of said head, said figures being drawn on a larger scale.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents a brine-supply pipe, which is connected with a refrigeratingmachine of any approved construction. The brine-pipe Ais provided with a number of T-shaped distributing pipes or heads B, which are provided in their vertical .meshing wires of the same.

'discharge-openings at the under sides of the heads B, three screens for each head B being shown in the drawings. Th ese screens are detachably suspended from the heads B by means of hooks e, which engage headed pins '0r eyes e at the ends of said heads. The brinedistributing screens D are connected with the openings d of the heads B by means of twistedwire shanks f, that are formed at the upper part of the screen by the twisting of the inter- On the twisted Shanks f are placed adjustable plugs F, that are inserted by their conical tapering upper ends into the discharge-openings of the heads B, so as to regulate the size of the dischargeopenings andcontrol thereby the quantity of brine that passes from the heads over the distributing-screens D. Each plug F is provided at its lower end with a clamp-screw f, by which it can be adjusted higher or lower on its wire shank f, as shown in Fig. 3. When a low temperature is desired to be kept up in the rooms to be cooled, a larger quantity of brine is required to be passed over the distributing-screens B. Consequently the plugs have to be adjusted lower down on the Wire Shanks, so that the size of the dischargeopenings is made larger and a freer flow of chilled brine obtained.' W'hen the temperature is not required to be very low, the supply of brine is diminished by adjusting the plugs higher on the Shanks, so as to nearly .or entirely close up the holes at the under side of the discharge-heads B, until, nally, the brine will be compelled to pass through the central openings ofthe plugs and. thence along the shanks and over the distributingscreen D. The brine is distributed uniformly over the wires of the distributing-screens and finally discharged at the lower part of the same into an inclined trough G, by which IOO itis conducted back into the refrigeratingmachine for being rechilled and sent out again through the brine-supply pipe A to the discharge -heads and distributing screens, whereby the circuit of the brine to and from the refrigerating-machine is kept up. The action of the distributing-screens D also purifies the air, inasmuch as any smells and impurities cont-ained in the same are deposited on the screens, owing'to the circulation of the air produced through and between the screens. The impurities are deposited on the screens, which thereby get slimy and require, therefore, to be cleaned from time to time. For this purpose one discharge-head B at a time is cut out by closing its valve b. The distributing-screens are then removed, taken out of the storage-warehouse or cellar, cleaned by washing, and then suspended again from the discharge-head,which is then turned on again, so as to throw the same into action. By arranging a suitable number of screens, according to the size of the room to be cooled, very eifective and economical cooling of the air is obtained without any loss of cold by frost on the brinecondueting pipes, which forms a great objection to the present refrigerating systems, owing to the loss of cold and the drip caused by the melting frost. Furthermore, the cold stored up in the chilled brine is utilized in a higher degree and in a more effective manner by its being distributed over a very large screen-surface than when the same passes only through coils arranged in the cellars or storage-rooms.

Having th us described my invention,l claim as new and desire to secure byLetters Patent- 1. The combination of a brine-supply pipe, discharge-heads connected with the same, said heads having rows of openings at the under side, distributing-screens suspended from said heads and provided with wire shanks, and adjustable plugs located on the wire shanks and extending into the openings of the heads, substantially as described.

2. The combination, with a valved brinedischarge head having rows of Openings at the under side, one row of openings alternating with the adjoining ones, of a number ol screens suspended from said head and provided with Wire shanks extending into the openings and with adj ustable plugs surrounding said shanks and having conically-tapering ends, and clamping-screws, substantially as set forth.

In testimony that l claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
